Belimo ZONE24NC-S Zone Actuator, Spring-Return, Normally Closed, 24V, w/ Aux Switch

Description

The Belimo ZONE24NC-S is a spring-return zone actuator engineered for dependable, fail-safe HVAC zoning applications. Designed to operate on both 24Vac and 24Vdc power supplies, this normally closed actuator automatically returns to the closed position upon loss of power, ensuring safe system operation and protecting conditioned spaces from unintended airflow.

Key Features

• Spring-return mechanism provides automatic fail-safe, normally closed operation
• Compatible with 24Vac and 24Vdc power supplies for flexible installation
• Integrated auxiliary switch for end-position feedback and system interlocking
• Compact, lightweight design suited for residential and light commercial zoning systems
• On/off control for straightforward zone damper management
• Belimo’s proven actuator technology for long service life and reliable performance

Application

The ZONE24NC-S is ideal for use in forced-air HVAC zoning systems where individual zone dampers must open on demand and close safely upon power loss or zone call completion. The built-in auxiliary switch enables the actuator to signal the air handler or zone control panel when the damper has reached its open position, supporting proper system sequencing and preventing short-cycling.
